Feature description

An option to share checklists as simple text.

It could be implemented using a radio dialog to choose between the different formats for sharing but I don't see any reason why anyone would want to share notes in JSON format.

Why do you want this feature?

So I can share it with people who don't use Fossify Notes e.g. my security guard.

Should the shared checklists indicate completion status?

• Completed: [x] or ✔
• Not completed: [ ] or ✗

Just adding my use case here. We use the app for our shopping list. We select/unselect repeating items and currently share our shopping list with screenshots from the app because it's the easiest/only(?) way to get the completion status exported

Should the shared checklists indicate completion status?

* Completed: `[x]` or `✔`

* Not completed: `[ ]` or `✗`
